Check the electrical side high tension wires and electric distributor (distributor is located on the front right side of the engine covered with in the plastic casing and record the values, then check if it is proper, clean with contact sprays and use contact fluid to reassemble the lines. Also do check the ignition coil for the right bank since that is the problem side.
